Genesis 21:23

Now therefore, I pray you, swear unto me by the Lord, since I have shewed you kindness, that ye will also shew kindness unto my father’s house, and give me a true token:

And Abimelech took sheep, and oxen, and menservants, and womenservants, and gave them unto Abraham, and restored him Sarah his wife.

The Lord do so and much more to Jonathan: but if it please my father to do thee evil, then I will shew it thee, and send thee away, that thou mayest go in peace: and the Lord be with thee, as he hath been with my father.

And Jonathan caused David to swear again, because he loved him: for he loved him as he loved his own soul.

And Jonathan said to David, Go in peace, forasmuch as we have sworn both of us in the name of the Lord, saying, The Lord be between me and thee, and between my seed and thy seed for ever. And he arose and departed: and Jonathan went into the city.

Swear now therefore unto me by the Lord, that thou wilt not cut off my seed after me, and that thou wilt not destroy my name out of my father’s house. And David sware unto Saul. And Saul went home; but David and his men gat them up unto the hold.

And David said to him, Canst thou bring me down to this company? And he said, Swear unto me by God, that thou wilt neither kill me, nor deliver me into the hands of my master, and I will bring thee down to this company.

Moreover I call God for a record upon my soul, that to spare you I came not as yet unto Corinth.

Thou shalt fear the Lord thy God, and serve him, and shalt swear by his name.

And Abram said to the king of Sodom, I have lift up mine hand unto the Lord, the most high God, the possessor of heaven and earth, That I will not take from a thread even to a shoelatchet, and that I will not take any thing that is thine, lest thou shouldest say, I have made Abram rich:

And I will make thee swear by the Lord, the God of heaven, and the God of the earth, that thou shalt not take a wife unto my son of the daughters of the Canaanites, among whom I dwell:

And they said, We saw certainly that the Lord was with thee: and we said, Let there be now an oath betwixt us, even betwixt us and thee, and let us make a covenant with thee;

Now therefore come thou, let us make a covenant, I and thou; and let it be for a witness between me and thee.

The God of Abraham, and the God of Nahor, the God of their father, judge betwixt us. And Jacob sware by the fear of his father Isaac.

For men verily swear by the greater: and an oath for confirmation is to them an end of all strife.

And thou shalt swear, The Lord liveth, in truth, in judgment, and in righteousness; and the nations shall bless themselves in him, and in him shall they glory.
